Dear Maintainer,

When I plug in my wired headphones into my laptop's headphone jack, no audio
plays. I have to adjust the volume by muting/unmuting or increasing/decreasing
the volume in order for any sound to come out. This is an annoying usability
issue and was not present in Bookworm, with Plasma 5.25.5.

Sorry, my email client bugged out and sent this again. You can delete this one.

Hi,
what you're describing sounds to me like a kernel issue, rather than an issue with the
graphical environment. When you're comparing the bookworm/trixie behaviour on your HW,
the bookworm->trixie upgrade (or reinstall) involves both the kernel and the graphical
environment, then have you performed any further test to rule out any other possible
software to be at fault but Plasma?

It could help in troubleshooting when you could check the behaviour with different graphical
environments, e.g. GNOME, XFCE, LXQt... a live system could help you with this test [1].
It would help also to check whether the issue persists on old/new Plasma/kernel combination,
but that's definitely going to be harder, then let's check whether the issue is specific to
Plasma or generic to all graphical environments.

Additionally, it would help to have the relevant journal log in this bug report: in order to
capture that, please execute "sudo journalctl -f" in a terminal emulator, then perform the
relevant steps (plug headphones, play audio in the "broken" state, adjust volume, play audio
in the "working" state) and close the journal capture with Ctrl+C.

Kind regards
Marco
